    Btrfs: Allocator fix variety pack · 0ef3e66b
    Chris Mason 提交于
    * Force chunk allocation when find_free_extent has to do a full scan
    * Record the max key at the start of defrag so it doesn't run forever
    * Block groups might not be contiguous, make a forward search for the
      next block group in extent-tree.c
    * Get rid of extra checks for total fs size
    * Fix relocate_one_reference to avoid relocating the same file data block
      twice when referenced by an older transaction
    * Use the open device count when allocating chunks so that we don't
      try to allocate from devices that don't exist
